| Short description | Acacia aneura +/- Eucalyptus cambageana, E. thozetiana, Eremophila latrobei tall shrubland on lateritic residuals |
| Structure code | Tall Shrubland |
| Description | Acacia aneura tall shrubland. Emergent Eucalyptus cambageana or E. thozetiana commonly occur. A low shrub layer, dominated by Eremophila latrobei, usually occurs. The ground layer is sparse and composed mainly of tussock grasses. Occurs on flat to undulating crests of dissected Tertiary sandstone ranges sometimes with a superficial covering of Quaternary sands. The soils are shallow to very shallow, red earths and lithosols. Silcrete and gravel are abundant on the surfaces of ridges and hills. Not a Wetland. (BVG1M: 23b). |

| Fire management guidelines | SEASON: Various (wet season or winter). INTENSITY: Low to moderate. INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Aim to exclude fire by fuel reduction in adjacent vegetation communities where possible. Undertake partial burns when necessary to reduce fuel loads and protect against severe wildfire. Burn with high soil moisture (i.e., after rain/storms) or in winter. ISSUES: Acacia aneura may be killed by high intensity fire. There is rarely enough fuel load to burn in these ecosystems. |
| Comments | 6.7.11: Largely restricted to the central north of the bioregion. Extensive sheet and gully erosion, and scalding in some areas with associated loss of topsoil and reduction in diversity of ground layer has occurred in remaining areas of this regional ecosystem (Mills, 1980, LU 58). |
